Referring toFIG. 5, the thumbnail displayed at the third leftmost position may be athumbnail corresponding to the third most recently captured image.

In addition, whenever the image is captured, the control unit 150 maydetect the quality of the captured image. The control unit 150 maydetermine the quality of the captured image based on at least one of adegree of light exposure of the captured image, a resolution of thecaptured image, a focal position of the captured image, and a size of asubject included in the captured image.

For example, the control unit 150 may determine that the quality of thecaptured image is high, when the degree of light exposure of thecaptured image is appropriate, the resolution of the captured image ishigh, the focal position of the captured image is appropriate, and thesize of the subject included in the captured image is appropriate. Onthe other hand, the control unit 150 may determine that the quality ofthe captured image is low, when the degree of light exposure of thecaptured image is excessively high or excessively low, the resolution ofthe captured image is excessively low, the focal position of thecaptured image is out of a normal range, and the size of the subjectincluded in the captured image is excessively large or excessivelysmall.

The sizes of the thumbnails in the photo reel displayed on the displayunit 120 may be substantially equal to each other or different from eachother. For example, as the quality of the captured image becomes higher,the thumbnail corresponding to the captured image may be displayed in alarger size. In addition, as the quality of the captured image becomeslower, the thumbnail corresponding to the captured image may bedisplayed in a smaller size. In other words, the size of the displayedthumbnail may be proportional to the quality of the image correspondingto the thumbnail.

For example, referring to FIG. 5, the thumbnail displayed at theleftmost position in the photo reel may be smaller than the thumbnaildisplayed at the second left most position and larger than the thumbnaildisplayed at the third leftmost position. Therefore, the quality of theimage corresponding to the thumbnail displayed at the leftmost positionmay be lower than the quality of the image corresponding to thethumbnail displayed at the second leftmost position and higher than theimage corresponding to the thumbnail displayed at the third leftmostposition.

On the contrary, as the quality of the captured image becomes lower, thethumbnail corresponding to the captured image may be displayed in alarger size. In addition, as the quality of the captured image becomeshigher, the thumbnail corresponding to the captured image may bedisplayed in a smaller size. In other words, the size of the displayedthumbnail may be inversely proportional to the quality of the imagecorresponding to the thumbnail.

As described above, the image display apparatus 100 may display thethumbnails corresponding to the captured images in different sizesaccording to the qualities of the captured images. In other words, theimage display apparatus 100 may display visual marks indicating thequalities of the captured images through the thumbnails of the capturedimages. In this way, the user may quickly and easily confirm the qualityof the captured image. In addition, the user may intuitively confirm thequality of the captured image.

In addition, the types of the images corresponding to the thumbnails inthe photo reel, which is displayed on the display unit 120, may be equalto each other or different from each other.

An image corresponding to athumbnail displayed at the second leftmost position may be a burstimage. An image corresponding to a thumbnail displayed at the thirdleftmost position may be a still image. An image corresponding to athumbnail displayed at the fourth leftmost position may be a video.

Therefore, the type of the image corresponding to the thumbnaildisplayed at the leftmost position may be the same as the type of theimage corresponding to the thumbnail displayed at the third leftmostposition. In addition, the type of the image corresponding to thethumbnail displayed at the leftmost position may be different from thetype of the image corresponding to the thumbnail displayed at the secondleftmost position.

Referring to FIG. 2 again, in operation S130, the subject included inthe captured image may be recognized through face recognition. Wheneverthe image is captured, the control unit 150 may performed the facerecognition on the captured image.
